Transform

Detail solution

Apply the product rule:

$\frac{d}{d x} f{\left(x \right)} g{\left(x \right)} = f{\left(x \right)} \frac{d}{d x} g{\left(x \right)} + g{\left(x \right)} \frac{d}{d x} f{\left(x \right)}$

$f{\left(x \right)} = 3 x + 2$ ; to find $\frac{d}{d x} f{\left(x \right)}$ :
1. Differentiate $3 x + 2$ term by term:
  1. The derivative of a constant times a function is the constant times the derivative of the function.
    1. Apply the power rule: $x$ goes to $1$
    So, the result is: $3$
  2. The derivative of the constant $2$ is zero.
  The result is: $3$
$g{\left(x \right)} = \log{\left(x \right)}^{3}$ ; to find $\frac{d}{d x} g{\left(x \right)}$ :
1. Let $u = \log{\left(x \right)}$ .
2. Apply the power rule: $u^{3}$ goes to $3 u^{2}$
3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \log{\left(x \right)}$ :
  1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
  The result of the chain rule is:
  
  $\frac{3 \log{\left(x \right)}^{2}}{x}$
The result is: $3 \log{\left(x \right)}^{3} + \frac{3 \cdot \left(3 x + 2\right) \log{\left(x \right)}^{2}}{x}$
Now simplify:

$\frac{3 \left(x \log{\left(x \right)} + 3 x + 2\right) \log{\left(x \right)}^{2}}{x}$

The answer is:

$\frac{3 \left(x \log{\left(x \right)} + 3 x + 2\right) \log{\left(x \right)}^{2}}{x}$
